The report, known as the Climate Science Special Report, determined that it's "extremely likely" that over half the temperature rise recorded over the past four decades is linked to human activity such as tailpipe, smokestack and other industrial emissions.
The New York Times obtained a striking new report on the climate crisis that, under normal circumstances, we wouldn't yet be able to read.
The paper also said "those who challenge scientific data on human-caused climate change" are anxious the report will be publicly released. They noted how the number and severity of cool nights have decreased since the 1960s and how warm days and heat waves have become more common.
In its report, the Times acknowledges that the EPA still has until August 18 - over a week - to approve the report.
Attention to the climate change report comes more than two months after Trump announced on June 1 that the U.S. would pull out of the 2015 Paris climate agreement and a day after The Guardian reported that the U.S. Department of Agriculture has begun to censor the term "climate change".
If current trends of greenhouse gas emissions continue, temperatures across the USA will likely continue to rise, with a projected increase of 5 to 7.5 degrees Fahrenheit (2.8 to 4.8 degrees Celsius), The New York Times reported.
Policy recommendations were not included in the study, but it emphasized the need to stabilize the global mean temperature increase to 2 degrees Celsius by significantly cutting carbon dioxide levels. It projects a near-term rise of temperature in the USA by 2.5 degrees F (1.4 degrees C).
A preliminary draft of the new report was distributed for review last December and available on the website of the National Academy of Sciences, which has already approved it. We are living, right now, contending with more and increasingly brutal climate events - floods, droughts, heat waves and hurricanes - mostly of our own man-made doing.
The scientists involved in releasing the leaked document - the fifth draft of the 2018 report - told the Times they were releasing the document early in draft form for fear that the Trump Administration and Trump's Environmental Protection Agency Administrator, climate change denier Scott Pruitt, would attempt to deep-six, or at least drastically revise their work and conclusions. He could permit the facts and findings to be published, a decision that would undercut his actions such as pulling out of the Paris climate pact to limit greenhouse gas emissions. The U.S. Environmental Protection Agency (EPA), now led by Scott "Polluting Pruit" is one of the agencies that has to approve it by mid-August.
